div overlap another though position of div is relative

Question

I have a chart made using d3.js : code for chart

I am trying to put this chart within a website. website

Problem is that one div overflows the other as can be seen in the website. I tried changing the position of the chart to relative from absolute.It doesnot work.

What may be the issue.Why is this happening ?Any idea.

fiddle related to the website : My code so far (experiment here)

css and d3 javascript Code for the chart as used in the website ( everything is available in above fiddle link) :

Answer 1

Remove the position css attribute entirely from the chart-wrapper

.chart-wrapper {
  width: 100%;
  height: 100%;
  background-color: #0d0d0d;
}

and edit the parent of chart-wrapper and add custom height. You can tune the height to make it fit correctly.

<div class="container" style="height:700px;">

I tested the same on your site via Chrome dev tools css manager. It no longer overlaps and sits properly.

Answer 2

你必须删除“ .chart-wrapper ”中的“ position：absolute; ”
